设置UITextField的placeholder的字体大小、颜

今天遇到一个需求需要UITextField的placeholder的字体较输入字体较小。

查一下资料有一下两种实现方式：

1. KVC

[moneyNumberTextField setValue:kRE_Font15 forKeyPath:@"_placeholderLabel.font"];

[textField setValue:[UIColor redColor] forKeyPath:@"_placeholderLabel.textColor"]; [textField setValue:[UIFont boldSystemFontOfSize:16] forKeyPath:@"_placeholderLabel.font"];

2. attributedPlaceholder

UITextField *textField = [[UITextField alloc] initWithFrame:CGRectMake(0, 0, 200, 200)];
NSString *holderText = @"请输入密码！";
 NSMutableAttributedString *placeholder = [[NSMutableAttributedString alloc] initWithString:holderText];
 [placeholder addAttribute:NSForegroundColorAttributeName value:[UIColor redColor] range:NSMakeRange(0, holderText.length)];
 [placeholder addAttribute:NSFontAttributeName value:[UIFont boldSystemFontOfSize:16] range:NSMakeRange(0, holderText.length)];textField.attributedPlaceholder = placeholder;
 [cell.contentView addSubview:textField];
